The Pacung mountain resort in the middle of Bali has breathtaking views. There are some very pleasant restaurants in the area to relax over a meal. The area is steep, so you will need to keep a close eye on the younger kids. There is also the Kintamani volcano to visit. The hawkers can be pretty persistent on tours so be prepared. 

These are everywhere and with a good tour guide you can learn a lot about the culture and history of the Balinese people. One temple is built on a beach - Tanah Lot - and it has a tour that ends at sunset so you can enjoy the view.

Anyone entering a Balinese temple will be required to show respect to the gods by dressing modestly. Skimpy clothing and shorts are unacceptable and you may be required to wear a sarong. These can often be hired at the temple. Sometimes you will be required to give a donation to the temple.
